To all whom it may concern: y

Be it known that I, WILLIAM A. PRINGLE,

a citizen'of the United States, residing at Niagara'Falls, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Printing Apparatus, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

- This invention relates to printing mechanism for preparing the web for the manufeature of sales books and the like.

One of the objects -of the invention is ;to provide simple and efficient means for perforating webs.

Other objects will be in part obvious and in part pointed out hereinafter.

' ments of my invention, Figure 1. is a transverse'sectlonal view taken through the delivery mechanism of a printing press, showing the said attachment applied thereto. Fig. 2 is a view in side elevation ofthe said attachment. Fig. 3 is a view in side elevation of the ma'le'perforating 'c linder. Fig. 4 is a similar view of the fema e perforating cylinder. Fig. '5 is avertical sectional view taken through the perforating cylinders showing-theposition of the parts when in inoperative relation. Fig. 6 is a similar view showing the position of the parts when in operative relation. Fig. 7 is a view in:

- perspective of the perforating device. Fi

' coacts with the perforating device.

8 is a similar view of the member whic Similar reference characters refer to 'similar parts throughout the several views of the:

drawings. y v V Referring now to the drawings, 1 ndi-' cates the side walls of a portion of aprlntin'g' press, which serve as supports forjthe several cylinders employed'for feeding and rinting upon traveling websv The mechanism constituting the printing press is not shown herein as the same constitutes no essential part of my, invention. -For the purposesof describing this invention, it will be understood, however, that feed rolls, which are indicated generally at '2, are adapted to deliver fromthe printing mechanism a pluralit o'fwebs A and B, which have been acte u on thereby, said webs traveling side by si e, but in difi'erenthorr zontal planes, between said rolls. This independent attachment or saiddevice, which is denoted generally by 8, as. shown in the drawings,'is attached to the side of the printing'lpress, as by means. of "clamp bolts 9, I

and the relation of this device to the press is clearly shown in Fig. 1 of the drawings.

The frame of the said device is comprised of a' pair of parallelly disposed walls 9' and 1( which form journal supports for the severalrolls and cylinders em loyed'thereinto effect the difierent operat1ons*up on the web C. This web, which is fedfrom asuit able source of supply, not herein shown, is

first received between a pair of drawing rolls -11 and 12, roll-11 being 5 ring-pressed toward roll 12 by means o a retractile s ring 13 and is dap'able' of being swung t erefrom, to allow the web to be inserted,

by means' of a handle 14. Web 0 then passes over roll 12 and between it and a similar drawing roll 15 and is received between a printing couple constituted by a plate cylinder 16 and an impression cylinder 17, which effects printing of any desired inscription upon the traveling web; The web isthen carried along impression cyllnder 17 to-be' engaged by the numbering devices carried upon a cylinder 18 whlch coacts therewith, the construction of. which is particularly described and claimed in my co- P d filed Dec er 5, 1906 of which lghlS appllcation is" a division. This ap lication subseq ently resulted in Patent 9 4,428, issued November 1,-1910. 1 f

being; acted upon by the The web after numbering mechanism is perforated by means of mechanism-carried by the pali of the we next passes. The perforating mechanism, as shown in Figs. 3 to 8 glclusive, comprises-a female cylinder 19 n a male cylinder 20 which mutually co-act with each application Serial Number 346,392 em matin' cylinders 19 and 20 between which other. Female cylinder 19, is provided .with

a -.longitudinal ly :extending recess within lateral edge'with a '10 forating points 26. These points, when the cylinders are rotated, enter between the posts forating blade capable of adjustment to carry blade 24 in an .outward direction by means of adjusting screws 27 extending ,transversely through the cylinder, said strip being held in adjusted position by means of set screws-28.1 Mounted in recess 29 of cylinder -is a strip 30 which constitutes a" 20 cleari g bar for the perforating points, said. strip ying in engagement with blade 24. This strip is heldin recess 29 by means of screws 31, which also extend transversely through the cylinder, and is urged in an outward direction by means ,of retractile springs 32, which engage'at their outer ends with the strip and at their inner ends with shoulders provided in' the.recess through which the screws extend. "-This clearing blade operates to force the web front the perforating points when the same are extending therethrough and prevents the web from being torn by said points when'i't is drawn from between the perforating cylinders by the drawin rolls, a

It will .accordingy be seen provided mechanism whereby the capacity (g a printing press of the above type may be 'i creased in an extremely simple andefli- 40 cient manner.- The attachment, while always in position to be utilized, may be thrown out at will without affecting any-of -the other operations of the. press. The numbering' of the web is effected in an accurate '45 and positive manner and-the construction of the perforating mechanism insures "that the web will not be 'torntor otherwise mutilated during the perforating operation.

As many changes could be made in the.

'aboveconstruction and; manfiy apparently widely ,difier'ent embodiment of this in-,'

- vention made without departing of strip '21." Strip 23 which carries the perthatv I have I from the scope thereof, it is' intended that Lall matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. jHavingxlescribed my invention, what I claim as new and desire to secure by Letters Patent'is: V 1. 'In perforating mechanism for traveling webs, in combination, a pluralityof mating cylinders, one of said cylinders being provided with a device having a plurality ofspacedmembers, the other of said cylinders having aflixed thereto a plurality of spaced members each of which carries a lurality of perforating points, means for a ]usting one ofthesets of spaced members toward and 1 from the other, saidperforating points being adapted to take between the spaced members upon the other of the cylinders wheusaid cylinders are mutually rotated whereby the web passing therebetween is adjacent and extending-parallel with said perforating points adapted to freethe said points from the web when said web has perforated thereby.

2. In perforating presses, in combination, amale cylinderrovided with a recess inwhich is set a b ade having a plurality of spaced iiiembers, each of which is provided with a pair of per-0 rating points, a female cylinder having a recess within which is seta comb device composed of squareteeth between each of the teeth of which one of said pairs of periorat- 1n cy inder adjacent the'perforatin points ofsaid blade adapted to be retracted? when said perforating means-is co -acting. to perforate a web, aiidspring means for forcing said by sai perforating points willqbe cleared of said web after each perforating operation.
